​

Two Goals

• Refactor ndn-riot’s encoding/decoding and security support
• https://github.com/Zhiyi-Zhang/ndn-riot
• https://github.com/Zhiyi-Zhang/ndn-riot-tests
• Let ndn-riot work on NRF52840

​

Refactor ndn-riot

Now you can use new ndn-riot encoding/decoding and security now

Contribution

• With previous ndn-RIOT, you
• Cannot decode Name TLV block, and some other TLVs
• Cannot successfully do ECDSA verification
• Prepare your packet with manual operations on raw byte array and offsets
• Do a large number of dynamic memory allocation
• Now you can
• Ndn-cxx like developer experience of encoding and decoding
• HMAC, Digest, ECDSA security support and they works perfectly ☺
• No dynamic memory allocation in encoding and decoding part

Let ndn-riot work on NRF52840

• We successfully let NDN-RIOT work with NRF52840 except the communication model
• We successfully run all the encoding/decoding unit tests, Data sign/verify unit tests, and AES encryption/decryption unit tests
• For now, cannot successfully let two nrf52 talk to each other using 802.15.4
